Civil construction rock wool board index requirements?
Civil construction rock wool board index requirements? Dacheng Xiangdong Insulation Refractory Material Factory 13473696600 15731614448 In civil buildings, especially in high-rise civil buildings, when using rock wool board as insulation material, rock wool board with relatively large compressive strength and peeling strength and relatively low water absorption should be used. Therefore, the selection of three-dimensional rock wool board is the most suitable, but because the three-dimensional process is more complicated, the price of rock wool board is also very high, which cannot be realized in practical engineering applications. Considering the price factor of rock wool board, the selection is made. The relatively moderate price of the pendulum rock wool board is currently the best solution. See Table 1 for technical indicators for rock wool board selection.
